FIELD OF THE INVENTION

The invention relates to a device for plumbing and method thereof. In particular, an improved one-piece device that provides a multi-use pipe assembly for use with a kitchen or bathroom sink that accommodates different size sewer pipes and different size drain pipes to facilitate quick and easy installation with a one piece device.

BACKGROUND OF THE INVENTION

All sinks utilize multiple plumbing connections to a drain system. This plumbing usually involves drain fittings to connect the conduit to a sewer pipe, a trap, or U-shaped portion of the conduit, and a fitting to connect the conduit to the sink. Kitchen sink drains normally use a 1.5 inch diameter drain plumbing while bathroom sinks and other low-volume drains normally use a 1.25 inch diameter drain plumbing. Further, sewer pipes have varying sizes and are most commonly 1.5 inch, 1.75 inch or 2 inch in diameter. Prior art plumbing, such as drain fittings and traps, provide for connection to a specific diameter drain and/or sewer pipe. Further, prior art plumbing involves multiple pieces with a lengthy, complicated and precise installation process. Such prior art plumbing devices require custom sections to allow the plumbing to attach to the specific drain and pipe being used. Further, rigid conduit sections are difficult to install and require multiple pieces that are dimensioned with little tolerance. Still further, the same plumbing pieces cannot be versatilely used for the plumbing under a kitchen sink as for a bathroom sink due to the difference in diameter of the sewer and sink drain.

Therefore, there is a need for a one-piece under-sink plumbing assembly that can be utilized with various size drains and pipes and allows for easy and quick installation.

SUMMARY OF THE INVENTION

The present invention provides a one-piece plumbing device that can be used both under a bathroom or kitchen sink to connect to the sewer pipe and allows an easy installation.

The plumbing device of the present invention comprises a vertical end, a flexible neck, a connection, a trap section and a horizontal end. The vertical end of the pipe has two concentric walls, the first wall has a one and a half (1.5) inch inner diameter and a smaller second wall having one and a quarter (1.25) inch inner diameter nestled therein. The first wall and the second wall allow connection to the vertical end to sink drains having different diameters. The flexible neck has a first end and a second end. The first end of the flexible neck is connected to the vertical end. The flexible neck is capable of extending up to sixteen (16) inches in any direction. The second end of the flexible neck is coupled to the trap section. The other end of the trap section is coupled to the horizontal end. The trap section has a rotatable joint that facilities maneuvering and ease of installation of the plumbing device. The horizontal end of the pipe has three concentric walls nested within. The outer wall has a two (2) inch inner diameter. Nested therein is the middle wall having a one and three quarter (1.75) inch inner diameter. Nestled therein is the inner wall, having a one and a half (1.50) inch inner diameter. The outer, middle and inner walls allow connection of the horizontal end to sewer pipes having different diameters. The horizontal and vertical ends optionally have rings or ribs to facilitate proper sealing around the sink drain and sewer pipe.
